I want to preface this post by saying that I did not come up with Scrap myself, but I love the mechanic. James Bartolotti debuted it in the comments section of a Goblin Artisans article. That said,
While I feel it could be a bit more splashy, I like the idea here. This is one you might draft if you've already grabbed one or two guys with Scrap, but it's not playable otherwise (literally). Let me know what you think about this, and if you have any better ways to implement it, I'll be glad to hear you out.
